A; further object of the invention is to.

providean automatictrunk lock in which the} locking members are mounted on the outerside of the trunk.

A further object of the invention is to provide an automatic trunklock which is of simple construction, is strong and durable and is well" adapted for the purpose described.

With the above and other objects in view the invention consists of the improved automatic .trunklock and its parts and combinations as setforth in the claims, and all equivalents thereof.

.Referringto the drawings. the numerals 10 and 11 indicate two sections of a wardrobe trunk and 12 the top cover: of one of the sections. The two sections are hinged together and are adapted to swing horizontally to open position whilethe' top cover. swings upwardly. The two sections are lockedtogether at two points by the improved automatic look while the top cover is locked to its section by a keyed lock 13 inv the ordinary manner. The lIIlPFOVBCl'.lOCl ing: means for. the two sections comprises an upper keyed'lock 14' and a' lower lock 15 controlled by the movement of the upper lock 14. The upper lock lt'i'smounted on the section 10 and is formed with a hasp portion 16" adapted r to swing into locking engagement with an escutcheon. plate 17 mounted on' the upperportion of the other trunk .section. The lockportion 18 of the hinged hasp. 16 is controlled by akey 19. A slidabl'e member 20. positioned within: the trunk section and guided by the bracket 21 is connected to one endiof a link 22' andtlie' other end of the link is connected to the arm 23. carried by the hasp portion 16*and extending through-a slot formed'in the trunlrSO section 10. As the link is hingedly connectedlto' the slidable member and to the hasp; arm 23 any movement ot'the armwill reciprocatelthe slidableunember 20. A bell crank lever'QAt-js fulcru-med within the trunk section 10 andiits upper slottedend 25 is pivotally connected to the slidable member 20.. A. connecting bar 26 vertically eiitendfingi within the trunksection lOand guided in brackets-27 is pivote-dl at its upper end. to the lower end 28,.of thebell crankleverfl i and is reciprocated' thereby. The lower lock or latch. member; 15 comprises a'rectangular casing'29 within which extends the reciprocalv and pivotal hookmember'30. The said hookme'mber'. is of angular formation and is providedwith a rack portion 3lwhich is engaged :by a partial gear'32 journaledwitlr in the casin 29.. The hook portion 33' extends'downwardly andis positioned'tou 611 gage the coactingi locking me baa mounted onlxthebther' trunk section-i The hook.

member is also formed \vitl' an angular dge which slidingly engages the edge portion 29 of the casing 29 to swing the hook portion 33 upwardly and disengage the locking member 34 when the hook member is moved to unlocking position. In moving to unlocking position the hook men'iber will push against the locking member 3% and initially separate the trunk sections, and in looking the sections the hook member will draw the sections into intimate engagement with each other. A lever arm positioned within the trunk section 10 is mounted relatively fast at one end on the inner end of the shaft portion 36 of the partial gear 32. The outer end of said lever arm is piv otally connected to the lower end portion of the connecting bar so that when the hasp member 14 is swung to its outer or inner position the hook member 30 will be automatically moved to open or closed position, and in moving the trunk sections will be forced apart or drawn together as before described.

To permit the hook member 30 to swing upwardly when moved outwardly the lower inner edge portion 37 of said member is curved as indicated.

From the foregoing description it will be seen that the automatic trunk lock is of very simple construction and is well adapted for the purpose described.

WVhat we claim as our invention is:

1. In an automatic trunk look, a pair of spaced lock mechanisms, one of which is provided with a pivoted hasp portion, a slidable member moved by the hasp portion, a bell crank lever connected to the slidable member, the other of the lock mechanisms having a slidable and tiltable hook member, and a bar member connecting the bell crank lever to the hook member for moving said hook member when the hasp portion is moved.

2. In an automatic trunk look, a pair of spaced lock mechanisms, one of which is pro vided with a pivoted hasp portion having an inwardly extending arm, a slidable member having a linked connection with the arm, a bell crank lever connected to the slidable member, the other of the lock mechanisms having a hoo; member formed with rack teeth, a toothed member engaging the rack teeth and having an arm, and a bar member connecting the bell crank lever to the hook member for moving said hook member when the hasp portion is moved.

3. The combination with a trunk having two hinged together sections, of a means for locking the two sections together, comprising an escutcheon member mounted on one of the sections, a hasp lock carried by the other section and engageable with the es cutcheon member and also having an arm which extends through the section, a slidable member mounted within the section having the hasp lock, a link connected to the lock arm and to the slidable member, a bell crank lever positioned within the hasp lock trunk section and pivoted to the slidable member, a lock member mounted on the hasp lock trunk section in spaced relation to the first mentioned lock and having a hook portion engageable with the other trunk section and also having a toothed portion, a toothed member engaging the toothed portion and having an arm positioned within the. trunk section, and a bar member connected to the bell crank lever and to the arm of the toothed member for moving said hook member when the hasp member is moved.

i. The combination with a trunk having two hinged together sections, of a means for locking the two sections together, comprising an escutcheon member mounted on one of the sections, a hasp lock carried by the other section and engageable with the escutcheon member and also having an arm which extends through and into the section, a slidable member mounted within the section having the hasp look, a link connected to the lock arm and to the slidable member, a bell crank lever fulcrumed within the trunk section and having one of its arms pivoted to the slidable member, a lock member mounted on the hasp lock trunk section in spaced relation to the hasp lock and having an angular hook portion engageable with the other trunk section and also havin a toothed portion, a toothed wheel engaging the toothed portion and having an arm positioned within the trunk section, and a vertically extending bar member connected at its upper end to the bell crank lever and at its lower end connected to the arm of the toothed wheel for moving the hook member into and out of engagement with said other trunk section.

5. The combination with a trunk having two hinged together sections, of a meansv for locking the two sections together, comprising an escutcheon member mounted on one or the sections, a hasp lock carried by the other section and engageable with the escutcheon member and also having an arm which extends through and into the section, a slidable member mounted within the sec-- tion having the hasp lock, and havinga projecting pin, a link pivotally connected to the lock arm and to the slidable member, a bell crank lever fulcrumed within the trunk section and having one of its arms pivoted to the slidable member by a slotted engagement with the pin of the said slidable member, a lock member mounted on the hasp lock trunk section in spaced relation tothe hasp lock and having an angular hook portion engageable with the other trunk section and also having a toothed portion, said lock member also having an inclined edge portion for directing the member to an unlocked position, a toothed Wheel engaging the into and out of engagement With said other toothed portion and having an arm positrunk section.
